EXCLUSIVE: Pixie Lott says she is ready to smash her way back into the charts as she prepares to debut her brand new single on live TV on Thursday night.

The pop babe – who turns 23 this Sunday – also says her boyfriend Oliver Cheshire, 25, has made it easy for her to write and record music about love on her upcoming third album.

‘It’s my first time writing from the actual experience of being in a relationship. It has really helped,’ the blonde beauty told Guilty Pleasures in an exclusive chat, adding she has found writing from the heart easy to do.

‘I can relate to every aspect of what I’m singing – the good times and the bad times. I love writing about things that I experience. It makes songs greater,’ she said.

And while Lott certainly has beauty and music talent in spades, it would seem her model boyfriend only has one of these two qualities.

‘Oliver can’t sing! He tries. He thinks he is a bit of a DJ and he loves music, but he’s not really a singer. We’ve never even done karaoke. Will he be stealing my thunder? No!’ she laughed.

The singer will be performing her new single – titled Nasty – on the Brits are Coming on ITV on Thursday night as the nominees for the 2014 Brit Awards are unveiled.

‘It’s a funky, soulful track that is very up-tempo and fresh,’ she says of the single – which she also revealed she had to fight for after it was originally recorded (but ultimately rejected) by Christina Aguilera, sparking a bidding frenzy among her music contemporaries.

‘A few other singers had recorded it and Christina was one of them so everyone wanted this song. When I heard other singers had done it I thought “I need to get this!” It was a difficult song to get because there are so many old-school samples on it, like James Brown, that are hard to clear copyright on. But I got it and now it is my new single.’
